Ventral view: chambers moderately inflated; intercameral sutures radial, narrow but deeply incised, meet at closed umbilicus. Lateral view: keeled periphery, very thick on early chambers of final whorl; dorsal face slightly concave; ventral face concave adjacent to periphery, inflecting to weakly convex, continuing to umbilical shoulder which covers umbilicus; aperture an umbilical--extraumbilical interiomarginal low slit, slightly higher near periphery; keel distinctly flexed axially. Wall finely and densely perforate, smooth, but heavily encrusted. Size: Length 650 µm; width 565 µm; height 320 µm Etymology: Latin, spurius, false; second component refers to 'Pulvinulina menardii var. tumida Brady'.
